| -5- Rm{William Robotham - Chief Engineer}6/R.18.8.38. (14) We are working with Ferranti's with the object of producing a satisfactory all-British wireless installation for B.50. (15) We are developing simplified heating schemes for saloon cars. (16) Tyre tests are being made to produce a satisfactory Avon tyre for noise and cornering ability. (17) We are producing a reserve petrol tap on the tank that can be electrically operated by a switch on the instrument board. (18) Fuel economy is continuing to receive attention. A duplex induction pipe is being developed to give high gas velocity at low speeds and yet effective breathing at high speeds. (19) Progress continues to be made improving the efficiency of exhaust systems. (20) Sparking plug point burning is receiving attention. Rm.{William Robotham - Chief Engineer} | ||
